I have this basic function to convert my unix timestamps into a date string. I have seen that it returns the wrong month (29-10 instead of 29-11). I was able to reproduce it on JsFiddle. What could be the problem?
function unixTime(unixtime) {
var u = new Date(unixtime*1000);
return u.getUTCFullYear() +
'-' + ('0' + u.getUTCMonth()).slice(-2) +
'-' + ('0' + u.getUTCDate()).slice(-2)
// ' ' + ('0' + u.getUTCHours()).slice(-2) +
// ':' + ('0' + u.getUTCMinutes()).slice(-2) +
// ':' + ('0' + u.getUTCSeconds()).slice(-2)
}
var test = unixTime(1638178329);
console.log(test);
You can use Date.toLocaleDateString() to format strings in the desired format. Selecting a locale of 'sv' will give you ISO dates and selecting the 'UTC' timeZone will give the correct timezone.
function unixTime(unixtime) {
return new Date(unixtime * 1000).toLocaleDateString('sv', { timeZone: 'UTC'})
}
console.log(unixTime(1638178329))
console.log(unixTime(Date.parse('2021-05-04')/1000))
console.log(unixTime(Date.parse('2015-12-25')/1000)).as-console-wrapper { max-height: 100% !important; top: 0; }
